Generalized coordinated multipoint framework for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2021)
The characteristic feature of 5G and beyond networks is the diversity of services, which is required to support different user needs. However, the requirements for these services are often competing in nature, which impresses ...
New physical layer key generation dimensions: Subcarrier indices/positions-based key generation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this letter, novel algorithms for secret key generation from the wireless channel in multi-carrier systems are proposed for ensuring the confidentiality and authentication in wireless communication systems. The novelty ...
Performance analysis of OTFS under in-phase and quadrature imbalance at transmitter
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
The influence of in-phase and quadrature (IQ) imbalance on the performance of orthogonal time frequency space (OTFS) transmission is investigated in this work. OTFS is a recent two-dimensional transmission scheme with ...
Comparison of clinical and laboratory features and treatment options of 237 symptomatic and asymptomatic children infected with SARS-CoV-2 in the early phase of the COVID-19 pandemic in Turkey
(National Institute of Infectious Diseases, 2021)
Since the first report of COVID-19 in December 2019, little is known about therapeutic usage of hydroxychloroquine in pediatric patients with COVID-19. We retrospectively retrieved data for SARS-CoV-2 PCR positive pediatric ...
Flexible numerology in 5G NR: Interference quantification and proper selection depending on the scenario
(Hindawi Ltd, 2021)
The 3rd Generation Partnership Project (3GPP) adopted cyclic prefix OFDM (CP-OFDM) for both uplink and downlink communications (although DFT-s-OFDM is also allowed in the uplink) in 5G New Radio (NR) Release 15. However, ...
Efficient spectrum occupancy prediction exploiting multidimensional correlations through composite 2D-LSTM models
(MDPI, 2021)
In cognitive radio systems, identifying spectrum opportunities is fundamental to efficiently use the spectrum. Spectrum occupancy prediction is a convenient way of revealing opportunities based on previous occupancies. ...
A secure downlink NOMA scheme against unknown internal eavesdroppers
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
Enhancing security level against potential internal eavesdroppers in Non-Orthogonal Multiple Access (NOMA) has been reported as a serious challenge. In this letter, a novel secure NOMA scheme based on physical-layer security ...
Inter-numerology interference in OFDM-IM systems
(Wiley, 2021)
In 5G and beyond communication systems, distinct numerologies can coexist to serve diverse requirements for users and applications. However, the inter-numerology interference (INI) is a main challenge that significantly ...
A novel frame design for integrated communication and sensing based on position modulation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this paper, a novel frame design for integrated communication and sensing is proposed. The proposed frame structure consists of Barker radar sequence and binary phase shift keying (BPSK) modulated data bits. The temporal ...
Wireless communication, sensing, and REM: A security perspective
(Institute of Electrical and Electronics Engineers Inc., 2021)
The diverse requirements of next-generation communication systems necessitate awareness, flexibility, and intelligence as essential building blocks of future wireless networks. The awareness can be obtained from the radio ...
